Park矢量变换在异步电机故障诊断中的应用

Application of Park Vector Transformation in Fault Diagnosis of Asynchronous Machine

分析了异步电机系统中Park变换过程,应用矢量变换将三相定子电流转换为图形方式进行故障诊断,文中给出了故障形式与图形的关系,通过实例验证了该方法的有效性。

This paper analyzes the process of Park transformation in asynchronous machine system, and applies vector transformation to fault diagnosis by converting three - phase stator current to graphics mode. The relation between fault＇s forms and graphs is expressed subsequently. The experiment result demonstrates the validity of the method.
